Emergent gravitational dynamics in Bose-Einstein condensates

TL;DR

This paper presents a toy model demonstrating how non-relativistic gravitational dynamics can emerge from Bose-Einstein condensates, showing that low-energy behavior mimics modified Newtonian gravity.

Contribution

It introduces a specific Bose-Einstein condensate model where emergent non-relativistic gravity naturally arises in a certain regime, providing insights into gravity's emergence.

Findings

Low-energy dynamics are effectively described by a modified Newtonian gravity.

A specific regime in Bose-Einstein condensates leads to emergent gravitational behavior.

The model offers a simplified framework for studying emergent gravity phenomena.

Abstract

We discuss a toy model for an emergent non-relativistic gravitational theory. Within a certain class of Bose-Einstein condensates, it is possible to show that, in a suitable regime, a modified version of non-relativistic Newtonian gravity does effectively describes the low energy dynamics of the coupled system condensate/quasi-particles.
